The term astrobiology derives from Greek roots, this alludes to the study of the possible existence of life on other planets ", this is made up of" astro "which means" star "plus" bios "which means" life "and the suffix" lodge ”which is equivalent to“ study ”,“ treatise ”or“ word ”. Astrobiology is that science in charge of the complete study and analysis of life throughout the universe; In other words, it deals with the origin, how it is distributed and the future of life in the universe (extraterrestrial life and life on Earth). This discipline is based on the implementation of other disciplines such as biology, astrophysics and geology to resort to the investigation of the origins, in addition to the influence and presence of life on the planets.
It is known that since the first human beings looked towards the sky, their first idea of the stars was that they were like distant bonfires; which means that the human being has wondered throughout his life if we are alone in the Universe. The ancient Greeks argued against our planet, decreeing that it is the only support for life, but they lacked the technology to prove their beliefs. Later in the 20th century, the almost simultaneous discoveries of possible remains of bacterial life in a Martian meteorite, and the first planets to orbit other stars, raised questions of the existence of life beyond Earth to the forefront of the scientific work. In the 21st century, the new field of Astrobiology takes advantage of the technological and scientific capacity necessary to seriously address these ancient questions.
Astrobiologists can work alone on certain scientific questions, but there are several occasions that they work together to analyze complex questions, questions that cover topics such as: What type of environment is necessary for life to survive? How does the lifetime? Does life exist or has existed in our solar system elsewhere? What is the future of humanity on Earth and beyond? How did life originate? , among other.
